Application tiled March 24, 1919. Serial No. 284,550.

To all whom it may eoncern:

Be it known that 1, (i1-:onor: F. l `nnnn, a resident of Ben Avon, in the county of Allegheny und Stute ot' Pennsylvania, have invented a new and useful Improvement in Driving Connections to Washing-Machine Cylinders, of which the following is n speeitieation.

his invention relates ,to improvements in washing machines of the cylinder type, and partiell arly to the means for removably supporting the cylinder in the tub and connecting it with the member for rotating said cylinder.

rushing machines of the cdylinder or drum type usually have the cylin er or drum removably supported in the tub und operatively connected to the rotating menus in u manner to permit the cylinder to be disconnected from the rotating mennel and removed 'from the tub by tilting the cylinder and then liftinv it out of the tui. n removing the cylinders from the tub, und again replacing them therein, in this mannen it frequently huppens that the eylinders become jammed and mutilated to such an extent that a new cylinder must be supplied.

The objert ot' the present invention is to provide an arrangement o1' ports which permitsthe cylinder or drum to he lifted out of the tub with a straight rectilinear motion, ."without tilting` and therefore without liability of jamming or Inutiluting the cylinder; and which means provide for nutomatirally and securely locking the cylinder in operative relation to its rotating means.

ln the necompiuiying drawing Figure 1 is a vertical sectional view taken longitudinally through therylindervand through the. end walls of the tub and showing the mounting of the cylinder and its operating oonneetion with the rotating means: Fig. 3 is u vertical sectional view on the line 2f-2, ["ig. l. showing only the means for connecting the cylinder to its rotaiting means: and Fig. 3 is a. central vertical section through the parts shown in Fig. 2.

ln the drawiunr l and 2. represent the end walls of a suitably slumped tub, iu which is the rotnl'y cylinder The lower end of n hanger or socket 4 attached to one end wull of th'e tub and onen at its top forms a heuringfor the journal or trunnion 6 attached to the udiurent end of thelcylinder il. This arrangement pepmits the cylinder to be lifted out of the tub.

Extending through the 0p osite end wall 2 of the tub is a rotatable she t 7, which inay be either hand or power driven, referbly the latter, and, which prefer-abi) is connected to automatic reversing mee anisxn to periodically reverse the cylinder or-dr\1m, as is well known in this type of machine. l m the inner end of this shaft is the driving arm 8. having substantiallv parallel side edges, and provided at its end on its outer fuer, that is. the face toward the wall 2 of the tub, with a trnnsverse shoulder l0, and beyond the same with the beveled face ll. Secured to the adjacent end of the cylinder or drum is e Clutch member having u web portion 12 provided with holes 13, for reeeiv ing counter-sunk screws, rivets, or small bolts, for securing the sume to the cylinder, and being provided with parallel lungesl spaced u. )art a distance slightly greater than the width of the driving arm 8 and adopted to receive the driving arm therebetween, said flanges at their free ends curving outwardly, :is at 16, to provide n flaring entrance to cuide the clutch onto the driving arm. Trefernhly the side flanges 15 are provided neer their lower ends (that is the ends which are lowerniost when the cylinder is in position to be removed from the tub) with a bridge piece 17 which lies outside of ythe driving arm, as shown, and serves as a means to prevent displacement of the cylinder endwise relative tothe driving arm. Neer their opposite ends said angesare conneted by a transverse web 18 serving es e limiting' stop against which the end-0f the driving arm contacts when the vparts are nesembleg and beyond this are provided with dpair perforated bosses 19 for receivin the pivot or trunnion 20 of n locking latc Btwhieh on the inner face of its lower end is r'ovided with a hook 22. nnd beyond this wi li Il beveled foce 23. A compression sprin 24 isinter sed between the upper end o the latch am the clutch member, being seated at one end in a soeket in the latch und at its other end over e stud or boss 26 on the clutch member. The extreme upper endwofthl 10B latch is flattened and widenedr'to form the handle portion 27.

The parts 'are shown in assembled relation,`

in which the driving arm S on the Shaft 7 projects up into the groove between the side iinnges l5 of the, clutch member, with its upper end in contact with the transverse web 18, andbeing locked to said clutch member by means of the hook' on the latch 21 engaging over the' shoulder 10 of the driving arm. ythis 1iiieami'the drum is securely locked to the driving member, and cannot become detached therefrom'during Vitis rota-i Aout of the tiib in a straight rectilinear line.

To replace the drum, it is merely lowered down into the tub while 'the driving arm is vertical, thus causing the flared lower ends 1G of the clutch flanges to guide the parts into proper connecting relation, the mere downwardniovement of the drinn causing the beveled face 23 on the latcli to slide past the beveled face 11 on the driving arm, and causing the latch to `automatically interlock with the driving arm, as will be obvious.

The construction 'described rovides for removing the drum from the tu and again replacin the same therein, in straight rectilinear lines, thus obviating any danger of jamming or mutilatin the cylinder. The drum is securely locke to the rotating member and in a manner which permits of its ready unlocking therefrom, andto permit its automatic interlocking therewith.
